TTM = trailing 12 months: the last four reported quarters added together. "TTM to H1 2026" is the 12 months up to the latest quarterly or half-year report (H1 = to the end of June). Year 1 grows from there.

Past years and projection

Grey columns are reported results from the annual reports (after-tax EBIT at the model's tax rate), so you can check the growth and margin assumptions against the past. Years 1–5 are the model.

Cross-check: what the market has paid before

For cyclical businesses, analysts check a DCF against the multiples the stock has traded at through past cycles. Price / book is the usual anchor for them: P/E looks highest at the bottom of a cycle, when earnings are smallest, and lowest at the top. The price each band would give today:

LowTypicalHigh
Price / book (book value ₩13,849 a share)Now 0.73×₩13,9531.01×₩18,1671.31×₩33,7952.44×

Low, typical and high are the 10th percentile, middle and 90th percentile of month-end multiples since 2021, each against the latest report out by then, per share at today's share count; loss years and P/E above 100 are left out. Run-rate earnings are one quarter × 4, not a forecast. Model estimate based on the assumptions shown. Not a price target and not a buy or sell signal.
